The introduction of specific antisera has led to the replacement of total iron binding capacity assays with direct immunochemical measures of transferrin. However, some controversy exists over the effect of the degree of iron saturation on antigen-antibody interactions in these immunochemical assays. This study describes a simple automated immunoturbidimetric assay of transferrin, and includes a reference range and an evaluation of the effects of common potential interferents, including iron, bilirubin, lipemia, and hemoglobin. The measured and the calculated TIBC are also compared for 78 healthy individuals and 51 patients with anemia.

In order to investigate the influence of diabetes mellitus on immune complex-mediated nephritis , we produced Heymann nephritis in streptozotocin-induced diabetic rats (DM-HN group) in which the clinical course for 24 weeks and histological changes were examined. Nondiabetic rats with Heymann nephritis (HN group) and diabetic rats (DM group) were also examined as controls. The degree of proteinuria, hypoproteinemia, hyperlipidemia and anemia were more pronounced and the mortality rate was higher in the DM-HN group than in the HN group or in the DM group. Histologically, larger and more subepithelial or intramembranous electron-dense deposits as well as a more markedly thickened glomerular basement membrane (GBM) were observed in the DM-HN group than in the HN group. In conclusion, the nephrotic manifestations and histological changes in the GBM in Heymann nephritis were augmented by the association with diabetes mellitus.

Infection of 10-day-old chicken embryos with an avian retrovirus. Rous-associated virus type 7, resulted in a disease characterized by stunting and hyperlipidemia. By 20 days after hatch, infected chickens were smaller than hatchmates and developed ataxia and obesity over the next 30 days. Histological examinations of livers from infected chickens revealed a diffuse panlobular fatty infiltrate involving an accumulation of fat in microdroplets. Electron microscopic examinations of livers from infected chickens revealed hepatocytes with swollen mitochondria that lacked cristae. The thyroid and pancreas were infiltrated with lymphoblastoid cells by 1 week after hatch. An examination of the blood revealed a mild anemia, a frank lipemia, and high levels of uric acid. This syndrome induced by Rous-associated virus type 7 in chickens may be useful for elucidating the nature of several diseases, including that found in the fatty liver and kidney syndrome of chickens and that observed in a strain of obese chickens.

Intravenous miconazole can produce responses in patients with various manifestations of coccidioidal disease, even if they have failed to respond to amphotericin B. In 4 large series of 33, 33, 46 and 31 courses of miconazole for skin and soft tissue, chronic pulmonary, meningeal and skeletal coccidioidomycosis, response rates of 40, 72, 31 and 32%, respectively, were achieved; 60, 75, 78 and 56%, respectively, of those responding subsequently relapsed at the site(s) of earlier involvement. This suggests that the therapeutic effect of the relatively brief courses used (mean, 1 to 3 months) is fungistatic in vivo. Common side effects of intravenous miconazole include phlebitis, pruritus, anaemia, thrombocytosis, hyponatraemia, nausea, hyperlipidaemia, vomiting, central nervous system effects, and rashes. The place of miconazole relative to amphotericin B and ketoconazole has not been determined, and requires further comparative studies. Information on the results of different regimens, particularly longer courses, would also be of interest.

This paper is a study of 117 patients with endstage renal failure, treated by continuous ambulatory peritoneal dialysis (CAPD) over periods of 1-56 months. The study has shown CAPD to be an effective form of dialysis with a number of advantages over intermittent peritoneal dialysis and hemodialysis (better control of salt and water status, hypertension and anemia, steady state biochemistry and greater ease of self-dialysis). Peritoneal clearance and ultrafiltration have remained adequate in all but a few patients. Hypoproteinemia, poor nutrition, obesity and abdominal herniae have been problems in a small percentage of patients. Hyperlipidemia has developed in half the patients but improved with diet. Peritonitis remains the major barrier to the more widespread use of CAPD, although its incidence can be considerably reduced by use of better connectors, bacterial filters and choice of patients.

Bilateral corneal opacities are the first clinical sign of a familial lecithin-cholesterol acyltransferase (LCAT) deficiency and can be found in early childhood. Familial LCAT deficiency includes the following typical clinical findings: corneal opacification, proteinuria, anemia, turbid or milky plasma, very low plasma HDL, very low plasma cholesterol esters and lysolecithin, hyperlipidemia, and very low or absent LCAT enzymatic activity. Several patients have had fundus findings including angioid streaks and papilledema. This disease is autosomal recessive and has been reported in a total of 19 patients previously. Progression of the disease has resulted in premature atherosclerosis, renal failure and transplantation, decreasing visual acuity and corneal transplantation.

Oral contrceptives (OCs), usd by over 30% of reproductive aged women in Belgium, are by far the most widely used contraceptive in that country. The various types of OCs include monophasic, biphasic, and triphasic combinations of an estrogen and a progestin, sequentials containing estrogen only for 7-14 days followed by a progestin through the 21st day; macrodose or microdose progestin only formulations, 3-month injectable progestins, and the morning after pill. Side effects of OCs are mainly due to metabolic effects on coagulation factors, the renin-angiotensin system, glucose tolerance, or the lipid profile. Users of OCs face increased risks of cholelithiases, thrombophlebitis, thromboembolism, cerebrovascular accidents, myocardial infarcts (among smokers over 35 years of age), and hepatic adenomas. The most troubling secondary effect is the excess cardiovascular morbidity and mortality show by contraceptive users, not just those who are obese, hypertensive, or who have histories of vascular pathology, but also those over 40 years of age and smokers. Lenght of use of OCs does not increase vascular risks. Epidemiologic studies demonstrate that vascular risks are reduced in lower dose formulations. Absolute contraindications to OC use include serious cardiovascular problems, severe hepatic pathology, estrogen-dependent tumors, pregnancy and undiagnosed gynecologic problems, and significant hyperlipidemia. Relative contraindications include severe headaches, cholelithiase, previous cholestasis of pregnancy, severe renal disease, fibromyomas, benign breast disease, age over 40 years, smoking, surgery anticipated within 4 weeks, infectious mononucleosis, falciform anemia, and immediate postpartum and lactation. Epilepsy, diabetes, depression, and varicose veins are not strictly speaking contraindications but require additonal surveillance. Lower dose formulations should be prescribed if possible. OC users should be followed up every 6-12 months. Among other steroidal contraceptive methods, sequential OCs and high dose progestin-only formulations are used for short-term treatment of specific conditions. Progestin-only minipills are used when an OC is desired but estrogens are contraindicated. Injectable progestins should be reserved for patients who for cultural or medical reasons can use no other type of contraceptive. Morning-after pills should not be considered a regular form of contraception. If OCs are used in adolescents, a low dose pill is indicated. Low dose OCs may be indicated for diabetics because of the danger of infection with IUDs and the lesser efficacy of barrier methods. If OCs are used in epileptics, they should be regular dosed because of the danger of drug interactions. Only low-dose formulations and progestin-only minipills should be used by women over 40.

It is stimulating to ascertain the comparative risk to the woman of hormonal contraceptives of the various kinds used today: combination preparations, which rely on blocking the secretion of gonadotropic hormones by the hypothesis; sequential preparations, which rearrange the physiological relationships of the menstrual cycle; gestagen preparations (minipills), which heighten the viscosity of the cervical mucus; longterm injectable preparations, which initially block ovulation and then act on the cervical mucus; postcoital preparations, which act by inducing abortion of the fertilized egg. Of these the most reliable are the fixed combinations, while sequential preparations are somewhat less so. The minipills are the least reliable. Interaction with other medications can reduce the reliability of these preparations; for instance, women on contraceptives have become pregnant after taking antiepileptic medications containing phenobarbitol and hydantoin. As far as risk is concerned, we must distinguish between those that merely harm the woman and those that pose a threat to life. Some of the former are: bleeding between cycles, failure of menses to appear after cessation of contraception, depression, breast-pains, hypertension, thrombophlebitis, and reduced libido. Hormonal contraceptives also have a series of beneficial effects, especially in women who ordinarily have menstrual difficulties. Among the more serious side effects are: risk of teratogenicity, carcinogenicity, liver problems, thromboses, and infarctions. To reduce the risks of these various side effects, the physician should observe carefully the contraindications: these are both absolute (cerebrovascular and retinal problems, thrombo-embolisms, hepatic disease, diabetes, porphyria, and sickle-cell anemia and relative (migraines, cardiac pains, hyperlipemia, epilepsy, and multiple sclerosis).

The anemia observed in severe chronic lead poisoning is in part attributable to alterations in the erythrocyte physicochemical properties. Since they are partly related to the membrane lipid composition, the aim of the present study was to determine the effects of a triton-induced hyperlipidemia on the resistance to oxidation of erythrocyte membranes in lead-treated Wistar rats. Our results showed that triton administration to lead-treated rats induced an increase in erythrocyte choline phospholipid levels together with a significant decrease in the erythrocyte membrane lipid resistance to oxidation. These results led us to suggest that anemia in lead poisoning is linked to interactions between lead present in the membrane and plasma phospholipids. Their increase in rat hyperlipidemia induced by triton resulted in a decrease in the membrane resistance to oxidation and finally in an erythrocyte fragility leading to their destruction.

The effects of chitosan-coated dialdehyde cellulose (Chitosan DAC), a newly developed oral adsorbent of urea and ammonia, were examined in rats with progressive chronic renal failure (CRF) induced by adriamycin. CRF rats induced by repeated injections of adriamycin were fed a diet containing chitosan DAC (5% content) or Kremezin (5% content), an oral charcoal adsorbent (AST-120) under strict paired-feeding for four months. CRF rats that received both a normal diet and Kremezin showed progressive azotemia, hyperphosphatemia, hyperlipidemia, proteinuria, and anemia, and began to die from 9 weeks after feeding started. In contrast, chitosan DAC-treatment showed marked prolongation of the survival period and decreases in blood urea nitrogen, serum creatinine, and serum phosphate. In addition, chitosan DAC-treatment ameliorated anemia in CRF rats, although hyperlipidemia and proteinuria were not improved. Furthermore, fecal weight, fecal water content, fecal nitrogen and fecal sodium were markedly increased, and the apparent protein ratio was decreased in CRF rats fed a diet containing chitosan DAC for 9 weeks. In contrast, none of these effects were observed in CRF rats receiving Kremezin. These observations suggest the further possibility of using oral adsorbent therapy for CRF patients.
